However if it does, there usually is a setting in BIOS that needs to be turned on. On my D830 it was in the "Posting" section of Bios and was listed as "Virtualization Extension"

For laptops, this is indeed a tricky thing, but it's for workstations too. My laptop has a VT-x enable CPU, but my mainboard does not support nor provide a Virtualisation function. It might support it, but there isn't in the BIOS. Keep that in mind too.

My laptop supports intel VT, i have enabled it in BIOS but still i've got error
kernel requires an x86_64 cpu, but only detected an i686 cpu
unable to boot - please use a kernel appropriate for your cpu

Do you have any other virtualisation programs installed, like MS VPC? Only one virtualisation program can use the virtualisation extention at a time (run several VMs with one program can, but not in different programs with VT-x/AMD-V enabled for them).
